Tecnoflon® PL 557

About
TECNOFLON® PL 557 is a new generation low temperature peroxide curable fluoroelastomer with 65.5% wt fluorine content. Tecnoflon® PL 557 exhibits excellent low temperature flexibility (TR10 = -29°C), close to Tecnoflon® PL 455, but with improved chemical resistance and permeability. Like all other Tecnoflon® peroxide curable grades, it exhibits excellent processability; moreover it needs very short post-curing cycles. Some of the basic properties of TECNOFLON® PL 557 are: Excellent low temperature flexibility Low post cure Superior mold flow Lack of mold fouling Excellent mold release Tecnoflon® PL 557 can be used for injection, injection-compression and transfer molding of O-rings, gaskets and seals. This material can be extruded into hoses or profiles and can be calendered to make sheet stocks or belting. Tecnoflon® PL 557 can be combined with the cure system and other typical fluoroelastomer compounding ingredients. Mixing can be accomplished with two-roll mills or internal mixers.&&
